i written the trigger for auto create event from custom object, below is my code

trigger AutoCreateSfdcEvent on SVMXC__SVMX_Event__c (after insert , after update ) {
     List<Event> lstevent = new List<Event>();
   for(SVMXC__SVMX_Event__c se : Trigger.New){
     if(Trigger.IsAfter && Trigger.IsInsert){
      Event e = new Event();  
       e.StartDateTime = se.SVMXC__StartDateTime__c;
       e.EndDateTime = se.SVMXC__EndDateTime__c;
       e.Subject = se.Name;
       e.OwnerId=se.Owner.id;
       e.WhatId=se.id;
     //  e.AssignedTo= se.SVMXC__Technician__c.id;
       //e.WhatId = se.SVMXC__WhatId__c;
       //e.WhoId = se.SVMXC__WhoId__c;            
          lstevent.add(e);
     }
   }
    Insert lstevent;  
}
